Summary

Field measurements of depth-averaged flow velocity were acquired from the Tanana and Nenana Rivers near Nenana, Alaska, August 18, 2021, to support research on estimating surface flow velocities from remotely sensed data via particle image velocimetry (PIV). The velocity measurements included in this data release were obtained using a TRDI RiverRay acoustic Doppler current profiler (ADCP) deployed from a boat with an outboard motor. These data were collected along 7 cross-sections on the Tanana River and 7 cross-sections on the Nenana River; two passes across the channel were made at each cross-section. This data release provides depth-averaged flow velocities derived from the raw ADCP data using the TRDI WinRiver II processing software. [...]

Purpose

The purpose of this study was to assess the feasibility of estimating surface flow velocities from optical image sequences acquired from a fixed-wing aircraft flying along the river by tracking water surface features via particle image velocimetry (PIV). Remote sensing of flow velocities could provide a more efficient, cost-effective alternative to conventional field-based methods of measuring channel hydraulics and thus become an important component of non-contact approaches to streamgaging. Moreover, the ability to collect such data from a moving aircraft opens up the possibility of examining longer river reaches via remote sensing. This field-based data set was used to assess the accuracy of remotely sensed estimates of surface flow velocity derived from fixed wing aircraft-based optical image sequences via PIV.
